Numerical Methods and Implementation in Geotechnical Engineering explains several numerical methods that are used in geotechnical engineering. The first part of this reference set includes methods such as the finite element method, distinct element method, discontinuous deformation analysis, numerical manifold method, smoothed particle hydrodynamics method, material point method, plasticity method, limit equilibrium and limit analysis, plasticity, slope stability and foundation engineering, optimization analysis and reliability analysis. The authors have also presented different computer programs associated with the materials in this book which will be useful to students learning how to apply the models explained in the text into practical situations when designing structures in locations with specific soil and rock settings.This reference book set is a suitable textbook primer for civil engineering students as it provides a basic introduction to different numerical methods (classical and modern) in comprehensive readable volumes.

Easy Refract is the a software dedicated to the interpretation of seismic refraction surveys using the reciprocal method and the generalized reciprocal method (G.R.M.) The definition of the array geometry is extremely flexible and does not impose constraints on the number of shots to be used in the analysis. Easy MASW is a software for the interpretation and archiving of seismic data using the MASW method (Multi-Channel Analysis of Surface Waves). It is a very easy-to-use application that, with simple steps, performs the analysis of the shear waves velocities. The software allows the inversion using more modes. During the spectral processing phase the user can view the dispersion of a customizable synthetic model and the results are plotted directly on the velocity-frequency spectrum. The generation of the velocity-frequency spectrum has been improved to allow a more effective identification of modes. The user can select the points on which the inversion is performed directly on the velocity-frequency spectrum and assign to each point the mode to which it refers. ESD is a software for the check of earth small dams under both static and seismic conditions.

GDW analyzes walls in gabions, simple concrete weirs and GABIONS weirs in static ad seismic conditions. GDW has advanced graphics features including the three-dimensional view through which you can examine in detail the inputs made. Safety checks are carried out for load combinations defined by the user in accordance with the directives imposed by new regulations. GFAS (Geotechnical and F.E.M. analysis System) is a product for mechanical analysis of soil using finite elements methods. This is a complete solution that integrates all functions required for the analysis of geotechnical problem areas such as: Tunnels; Slope Stability; Excavations; Embankment settlements; Foundation Settlements; Interaction between structures and soils. Liquiter software is designed for soil liquefaction analysis and supports a wide variety of field tests. The results of the analysis are presented as: Safety Factor Soil Liquefaction / Probability of Soil Liquefaction; Cyclic mobility of clay; Liquefaction of sand and clay; CSR, variable CSR with depth from SHAKE results; Reconsolidation Settlement, Lateral Spreading; Residual Strength.... etc.
